In a small pot, bring some water to a boil. Place pears in a small colander, place strainer over boiling water (but not touching the water), and allow pears to be steamed.

In a second pot, combine water and mixed berries. Bring to a boil, then reduce heat. Cook gently for 5 minutes. Remove from heat and press cooked fruit through a strainer to get a thick fruit sauce. Set sauce aside.
